Abstract

Improved capabilities are described for taking a source digital file that is protected with a digital rights management facility, and converting the digital file into a file format suitable for use by a target application. In this case the target file format is different from the original file format of the source digital file, and the target application does not support the digital rights management facility of the source digital file. In addition, the file conversion process is performed in a secure processing facility that is supported by the target application.

Claims

exact text as granted — not AI-modified
1 . A method comprising:
 receiving a source digital file that is protected with a digital rights management facility;   converting the digital file into a file format suitable for use by a target application that is different from the original file format of the source digital file and that does not support the digital rights management facility of the source digital file; and   associating the file conversion process with a secure processing facility that is supported by the target application.   
   
   
       2 . The method of  claim 1 , wherein the target application does not support the structure of the digital file before conversion. 
   
   
       3 . The method of  claim 2 , wherein the secure processing facility is an encryption structure. 
   
   
       4 . The method of  claim 2 , wherein the secure processing facility is a use control structure. 
   
   
       5 . The method of  claim 1 , wherein the conversion preserves the rules mandated by the digital rights management layer of the digital file before conversion. 
   
   
       6 . The method of  claim 5 , wherein the conversion preserves the rules by providing secure transfer. 
   
   
       7 . The method of  claim 6 , wherein the transfer is of the digital file before conversion. 
   
   
       8 . The method of  claim 5 , wherein the conversion preserves the rules by providing secure processing. 
   
   
       9 . The method of  claim 8 , wherein the processing is of the digital file before conversion. 
   
   
       10 . The method of  claim 5 , wherein the conversion preserves the rules by limiting the usage of the digital file after conversion. 
   
   
       11 - 30 . (canceled) 
   
   
       31 . A system comprising:
 a source digital file that is protected with a digital rights management facility; and   a conversion facility for converting the digital file into a file format suitable for use by a target application that is different from the original file format of the source digital file and that does not support the digital rights management facility of the source digital file, wherein the file conversion process is associated with a secure processing facility that is supported by the target application.   
   
   
       32 . The system of  claim 31 , wherein the target application does not support the structure of the digital file before conversion. 
   
   
       33 . The system of  claim 32 , wherein the secure processing facility is an encryption structure. 
   
   
       34 . The system of  claim 32 , wherein the secure processing facility is a use control structure. 
   
   
       35 . The system of  claim 31 , wherein the conversion preserves the rules mandated by the digital rights management layer of the digital file before conversion. 
   
   
       36 . The system of  claim 35 , wherein the conversion preserves the rules by providing secure transfer. 
   
   
       37 . The system of  claim 36 , wherein the transfer is of the digital file before conversion. 
   
   
       38 . The system of  claim 35 , wherein the conversion preserves the rules by providing secure processing. 
   
   
       39 . The system of  claim 38 , wherein the processing is of the digital file before conversion. 
   
   
       40 . The system of  claim 35 , wherein the conversion preserves the rules by limiting the usage of the digital file after conversion. 
   
   
       41 - 60 . (canceled)
